A chemical complex of a biocidal agent such as ortho-phenylphenol and chlorpyrifos and a non-ionic polymer of 2-ethyl oxazoline (PEOx). The complex is compatible with and contained in a plastic film such as polyethylene, polypropylene and poly(vinyl chloride) and the product is characterized by a reduced rate of release of the biocide without adversely affecting either the properties of the biocide or the film itself. The biocide-impregnated plastic finds utility in bags and in packing used to inhibit fungicidal growth and to prevent attack by insects and bacteria during growing, drying, packing, shipping, storage and marketing of fruits and vegetables.

Novel nitrile functional glycol ether acetals that are useful components of hydraulic pressure transmission fluids are described.

Novel nitrile functional glycol ether acetals

Bicyclic amide ketals such as 1-aza-4,6-dioxabicyclo[3.3.0]octanes have utility as water or acid scavengers for addition to functional fluids.

Bicyclic amide ketal derivatives

Novel cyano- and hydroxyl-substituted cyclic compounds of the formula: ##STR1## wherein B, R, R' and R' are named substituents are disclosed.

Derivatives of cyano-substituted ketones and aldehydes

The distillative separation of a mixture of glycerine and glycerine-based acetal or ketal transesterification products is aided by addition of a borate ester-forming compound to the mixture prior to distillation.

Process for removing glycerine

Hydraulic fluids having high wet equilibrium reflux boiling points, good chemical stability and other desirable characteristics are made from certain cyano-substituted derivatives of cyclic ketals or acetals of the formula ##STR1## wherein A, B and R are specified radicals.

Hydraulic fluids containing cyano derivatives of cyclic ketals and

High yields of the title adducts are obtained from an essentially salt-free process comprising contacting at subambient temperature cyclopentadiene or a substituted cyclopentadiene with an aliphatic or an inertly-substituted aliphatic ester of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid, such as methyl acrylate, in the presence of a catalytic amount of base, such as tri-n-butylmethylammonium hydroxide. A novel class of Diels-Alder adducts are readily obtained by warming these Michael adducts; polyester compositions comprising the Diels-Alder adducts demonstrate good physical properties.
